(a) Electrical characteristics of compacted samples: CPE terms (in Ω⁻¹·Hz^-n unit) and CPE exponents , as a function of composition and for various temperatures °C; 10% error for and parameters. (b) Modeling parameters for sample as a function of temperature : resistances (in Ω), CPE terms (in Ω⁻¹·Hz^-n), (in s) and exponents . Three types of impedance models have been used to interpret the results. (c) Modeling parameters as a function of composition , at 700°C: resistances (in Ω), CPE terms (in Ω⁻¹·Hz^-n), (in s) and exponents n. Two types of impedance models have been used to interpret the results.
